[0057]FIG. 1 illustrates a device for surveying a surface 104 in the real world coordinate system 111. The device comprises a pattern projecting unit 101, an optical measurement system 102 and a processing unit 103. The pattern projecting unit 101 is adapted for projecting a predefined pattern 105 onto the surface 104. The optical measurement system 102 is adapted for determining positional and image data of a projected pattern 106 on the surface 104, wherein the image data are indicative of the predefined pattern 105 in a measuring coordinate system 112. The processing unit 103 is adapted for determining transformation data based on the predefined pattern 105 and the determined positional and image data of the projected pattern 106. The transformation data allow a transfor...
